我有
public class ExtendedBeanELResolver extends BeanELResolver {
private static final Pattern regExpDn = Pattern.compile("PLMN-PLMN/\\w+.\\d+(.*)");
@Override
public Object getValue(ELContext context, Object base, Object property)
try {
// remake DIST.NAME appearance
if (property.equals("dn") && base instanceof Alarm && ((Alarm) base).getCustomer().getNameEng().equalsIgnoreCase("mts")) {
String dn = null;
try {
dn = ((Alarm) base).getDn();
Matcher mtch = regExpDn.matcher(dn);
mtch.find();
((Alarm) base).setDn(mtch.group(1));
} catch (Throwable e) {
// logger.error("error in dn - " + dn);
} finally {
return super.getValue(context, base, property);
}
}
}
根据某些条件更改对象中的某些可见值。如果这是从 jsf 调用的,我不想更改值<ui:param name="fullDistName" value="#{alarm.dn}" />
我如何获取该 EL 调用的组件的 ID?对不起我的英语不好。
